In the Second World War, the Allies, which was led by Britain, ultimately defeat fascism Axis and win the war. There were many factors contributing to the Allies’victory, among which was intelligence warfare, which in a certain degree plays a very important role. This paper is to comb through the institutions, process and main measures of the intelligence warfare imposed by Britain on Germany, and summarize and evaluate the effect of the British intelligence war on the basis of a thorough investigation into Battle Of Britain, Battle of the Atlantic and Sicily Landing.The paper text is divided into four chapters. The first chapter presents the main British intelligence institutions before the Second World War. The second chapter mainly investigates the process and measures of the intelligence war imposed by Britain on Germany and the cooperation between the Allies and Britain. In the intelligence warfare imposed by Britain on Germany, Britain experienced a loss at first but later decoded German’s most confidential information, thus making the Allies obtain the German military trend timely and then make preparations for war. In order to maximize the access to German intelligence, British took all kinds of measures, mainly including sending spies, password deciphering, strategic deceive, radar reconnaissance, etc. In addition, Britain also cooperated with its allies and governments of neutral countries, fully carrying out the intelligence war with Germany. The third chapter is to investigate the intelligence war imposed by Britain on Germany in detail, taking Battle Of Britain, Battle of the Atlantic and Sicily Landing for examples. Battle Of Britain is a major battle of British home defense, in which mastering intelligence played a pivotal role; Battle of the Atlantic, which lasted throughout the World War Ⅱ, was a fierce clash between the wireless power grids of Britain and Germany; Sicily Landing followed the plan that the allied army of America and Britain was the main force, but "Meat" action was carried out by Britain from planning in the beginning to concrete implementation. In the intelligence war imposed by Britain on Germany, these three battles held very important positions. The fourth chapter discusses British achievements and the early loss in the intelligence war imposed by Britain on Germany and affirms its positive significance.In short, the intelligence war imposed by Britain on Germany in World War Ⅱ, which was affected by the policy of appeasement, won little success at first, but finally ended in a victory, thanks to British adjustment of its intelligence institutions and its adoption of diversified intelligence reconnaissance.
